Rachael is a British astronomer working at the University of Texas at Austin. She received her Bachelors in Mathematics and Physics with Astrophysics from King’s College London, her Masters in Astronomy from the University of Sussex and her PhD from Durham University before moving to Texas as a postdoc.
Her research focuses on the most distant galaxies, trying to understand how the earliest galaxies formed and the effect they had on the reionization of the Universe in its first billion years. Her specialty is gravitational lensing, whereby galaxies that are seen behind massive galaxy clusters appear magnified.
She is also heavily involved in public outreach as the co-founder and host of Astronomy on Tap ATX (@AoTATX), a series of free astronomy talks held in a bar in Austin. She will be hosting this event for the last time this week.
